ABSTRACT:

The US Navy is engaged with a variety of optical systems ranging from active lasers for
ship-defense to passive imaging systems. The interaction of light with the atmosphere has
a profound impact on the utility of all optical systems for the Navy. The atmosphere from
the ocean surface up through the top of the boundary layer presents a complex optical
propagation environment. I will discuss some of the optical effects we are interested in,
and the associated modeling approaches we use to understand and predict performance.
Our atmospheric characterization models must account for the local meteorology, and this
is done in different ways, ranging from relatively simple regression models to computationally
more intensive simulations based on numerical weather prediction (NWP). I’ll give an
overview of these methods and discuss their merits and shortcomings.
